Oddly, I called WallyWorld and asked for "a set of 31 x 10.5s." They told me they had some and I asked for a price, which they gave me - $125/tire. Not overly expensive, I thought.

When I got there, they pulled the truck in and began mounting a set of BFGs, so I asked the guy at the counter whether they were mounting the correct tire and he assured me they were. By the time all was said and done, still less than $600 for the set mounted and balanced with the fees, mop, slop, etc.

Of course now this IS the same place that claimed they couldn't find the right oil filter which which to perform an oil change too, so... <img src="/forums/images/graemlins/lol.gif" alt="" /> Take it for what it's worth.
